Psychologist on Susan Boyle's strange behaviour

London, (ANI): Susan Boyle"s increasingly strange behaviour is a result of the enormous pressure she"s facing after becoming an international sensation, says psychologist.

While writing in The Mirror, behavioural psychologist Jo Hemmings said that Boyle has been living her life in an absolutely different world than she's used to, making it difficult for her to cope. And it's worse for someone like Boyle who has psychological problems, he adds. She"s freaking out because she doesn't know how to act in situation.

Hemmings claims that 'Britain"s Got Talent" will have a lasting impact on Boyle. The recent outburst when judge Piers Morgan said Shaheen Jafargholi was in with a chance of winning was the outcome of the feeling of betrayal, because Piers was such a great fan of hers.

She's trying to act how she thinks she should act in that scenario. It looks awkward and uncomfortable and doesn't come naturally to her. Hemmings said that winning will be the best option but her outbursts will affect her chances because we're looking at her with less affection now.

He said she never expected to win when she first entered but has an artificial selfbelief that has been put on her by other people. She's now convinced she'll win - and that's part of her problem, Hemmings added.
